Hi, I'm glad to say I managed to get the problem sorted out! I phoned my PC guru.....decribed the problem...."Did you check your midi setting....channels , patches Etc.?" DOH! How could I have forgotten the most obvious! Went though all the files again...made corrections....all are playing the way they should now. I was sent off to bed without any hot chocolate! But I know you guys would have picked up on the problem anyway.....so thanks for thinking about it! Joe G.
